Feed additive for improving color of egg yolk of laying hens and production method

Abstract

The invention provides a feed additive for improving the color of egg yolk of laying hens. The feed additive is prepared from, by weight, 42-44 parts of orange peel powder, 11-13 parts of soy bean dregs powder, 35-37 parts of flavedo powder, 24-26 parts of apple seed powder, 6.5 parts of Northern kephyrion and 5 parts of auxiliaries. The production method includes the steps that all raw materials are dried in the sun or dried in a baking mode, the water content is 10-13%, and the raw materials are crushed into coarse powder ranging from 60 meshes to 80 meshes; all the raw material coarse powder are mixed in proportion and the evenly mixed with the auxiliaries; a high-energy vibration mill is utilized for processing the mixture for 15-30 minutes, then the downtime is kept for 2.5 minutes, then processing is conducted for 12-13 minutes, all raw materials generate different solid state mechanical chemical reactions twice and sieved through a 400-mesh sieve, and a finished product is obtained. By means of the feed additive, carotenoid and the like in orange peel, bean dregs and flavedo can be dissolved out effectively the color of egg yolk of laying hens can be remarkably improved, waste is changed to be valuable things, and recycling economy is developed.

Description

technical field [0001] The invention relates to a feed additive, especially a feed additive for improving egg yolk color, and also relates to a production method of the feed additive. Background technique [0002] Egg yolk color is one of the most important items in egg production indicators. The depth of egg yolk color is directly related to the sales method and sales volume of commercial eggs. For example, processed eggs with high added value, such as salted eggs and preserved eggs, require darker egg yolks, while fresh eggs with egg yolks less than grade eight cannot be exported to earn foreign exchange. Even in the domestic market, they can only be sold at a lower price. Meager, difficult to enter the high-end market. The pursuit of darker egg yolk color is not an irrational consumption habit of consumers. The darker egg yolk color indicates that some of the nutrients are indeed richer (except those made by chemical synthetic dyes such as Sudan red and Jialisu red). Un...
